Explore Mermentau, Louisiana, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Mermentau, Louisiana. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of Louisiana or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Mermentau.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Mermentau anchors itself firmly upon the flat, alluvial plains where the slow, deliberate pulse of the Mermentau River dictates the rhythm of the horizon. It lies 12.5 miles west of Crowley, LA (from Crowley, LA: bearing 262°T), and is situated 5.0 miles east-southeast of Jennings. The landscape stretches out in broad, unbroken expanses of dark earth, where the moisture in the air clings to the skin like a humid shroud as the sun descends toward the western fields. To the north, the elevation shifts ever so slightly, a subtle tilt in the topography that separates these low-lying expanses from the distant, modest rise of Onion Hill. The light at dusk here possesses a peculiar, syrupy quality, turning the sky into a bruised plum color that reflects off the quiet, dark waters of the riverbed, lending a sense of permanence to the expansive, open sky.
Mermentau owes its persistence to the fertility of these soils, which have long supported a quiet, industrious economy rooted in the cultivation of rice and the seasonal labor of the fields. Beyond the immediate reach of the town, the land opens into the expansive stretches of Laurents Pasture, a reminder of the agrarian heritage that continues to define the local character. Travelers passing through the region often find a brief moment of pause at the I-10 Rest Area, a small island of transit amidst the quietude of the surrounding acreage. Life in Mermentau moves with the deliberate pace of the seasons, characterized by a deep-seated resilience and a heritage that favors the steady labor of the land over the clamor of larger, more frantic centers of commerce.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
